Technical Abstract

A system for diverting an optical component signal from a multiplexed optical signal includes an optical communications channel having a first portion and a second portion. A multiplexed optical signal having a plurality of component signals may be transmitted through the optical communications channel. Each component signal lies within a different optical bandwidth. The system also includes a branch optical channel having a first section and a second section. A signal diverter that optically couples the first portion of the communications channel to the second portion of the communications channel directs a diverted portion of the multiplexed optical signal into the first section of the branch optical channel. The signal diverter also allows a non-diverted portion of the multiplexed optical signal to propagate into the second portion of the optical communications channel. An optical wavelength separator that is optically coupled to the first section of the branch optical channel separates a selected component signal from the diverted portion of the optical signal. The optical wavelength separator also optically couples the selected component into the second section of the branch optical channel. A port that is optically coupled to the second section of the branch optical channel allows the optical coupling of an optical device to the second section of the branch optical channel.
